[Patter Solo (The Learned Lecturer)]
Attend, attend, ye thoughtful folk, to matters most atomic,
A tale of Greeks who carved with words in fashion quite Platonic!
From temnein sprang the slicing art, from tomos came division,
Add alpha privative in front, and presto, no incision!

Atomos! Uncuttable! Philosophic brick!
A unit indivisible, precise and rather thick!
Democritus declared it so, with speculative glee,
Though lacking glassware, balances, or gasometry!

[Chorus of Victorians:]
Uncuttable! Unshatterable! Secure from any schism!
Until the modern chemists brought analytical realism!

[Orchestral Diversion and Clarinet + Oboe Duet]

[Lecturer:]
Enter Dalton, mild of mien yet integer of creed,
Who weighed his airs and oxides with arithmetical speed.
He found in compounds, plain and neat, proportions most exact,
In twos and threes and fours and fives, no fractional abstract!

Compound atoms! Ratios stout!
Water two to one throughout!
If flour and sugar mix by weight,
Why not by particles innate?

[Chorus:]
For mass conserved and ratios firm
Suggest a corpuscular term!

[Lecturer:]
But gases danced rebelliously in volumes quite divine,
Avogadro dared propose their counts were uniform by line!
Equal volumes, pressure matched, at temperature the same,
Contain like numbers, molecule for molecule in frame!

Hydrogen in pairs cavorts!
Oxygen in twos resorts!
Thus water’s stoichiometric grace
Found symmetry in gaseous space!

[Grand crescendo]

Then Boltzmann strode statistical, moustachioed and grand,
Declaring entropy a count no man could countermand!
The higher states are sparsely filled, the lower thickly thronged,
Probability dictates the dance where once mere pudding longed!

[bridge]

exp of minus E on kT!
A thermal democracy!
No moral weight to order lent,
Just likelihood and gradient!

[Finale Chorus:]
So from the Greeks’ uncut idea,
Through Dalton’s measured clarity,
To molecular reality
Confirmed by microscopy!

Though fashions shift and labels bloom
From carbon chains to farmer’s broom,
The atoms hum, the molecules spin,
And entropy will always win!
